DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a harvester for root crops such as onions.

[0002]

2. Description of the Related Art Conventionally, there has been a harvester in which a foliage portion of a crop is sandwiched between a pair of left and right endless belts which are arranged opposite to each other in a front-rear, rear-height manner and pulled out from the ground. The harvester is provided with a weeding device and a scraping device in front of the endless belt so that the foliage can be properly clamped by the endless belt, and the endless belt is used to properly pull the crop from the ground by the endless belt. A digging device for digging an underground portion below the belt front end side is provided.

[0003]

In the above-mentioned harvester,
It is an object of the present invention to provide a harvester that can perform harvesting of a multi-cultivated crop cultivated on a ridge covered with a multi-film.

[0004]

According to a first aspect of the present invention, there is provided a harvester including a winding device for a multi-film covered with ridges. Harvest by acting on crops.

[0005] In the above case, the hole for seedling transplantation established in the multi-film moves toward the tip of the foliage of the crop as it approaches the harvesting operation part, and after the hole comes off from the foliage, the harvesting operation part is moved. By winding the multi-film on the reel of the winding device so as to act on the crop, it is effective that crops of multi-cultivation can be harvested simply by attaching the winding device to an existing harvester.

[0006] Further, a winding device for a multi-film covered with ridges may be provided, and the harvesting work section may act on the crop before the multi-film is wound by the winding device.

[0007] In the above case, the hole for seedling transplantation provided in the multi-film moves toward the tip of the foliage of the crop as it approaches the harvesting operation, and the harvesting operation is performed before the hole comes off the foliage. By winding the multi-film on the reel of the wind-up device so as to act on the crop, the multi-film to be wound works to weed and raise the foliage, so that the harvester does not need a weeding device. It is effective.

When weeding and raising the foliage with a multi-film to be wound, it is preferable that a scraping device at the front of the harvesting work section is applied to the foliage before the hole comes out of the foliage.

[0009] In any winding device for winding the multi-film before or after the harvesting operation is applied to the crop, the winding speed is the same as the moving speed of the harvester, but the over-stretching and slackening of the multi-film. In the case of the latter winding device, it is effective because weeding and raising of foliage can be properly performed by the multi-film.

In any of the winding devices for winding the multi-film before or after the harvesting unit is applied to the crop, the power source of the winding unit uses a dedicated power such as an electric motor or the power of the harvesting unit. In some cases, the former is preferable because the winding device can be easily handled as an attachment. The latter is preferable because a dedicated power source is not required and the above-described winding speed can be easily obtained.

[0011] Before or after the harvesting operation is applied to the crop, any winding device for winding the multi-film is detachably attached to the harvester so that it can be handled as an attachment. Harvests the crop as usual using the harvester with the take-up device removed, and only in the case of ridges covered with multi-film, crops the crop while winding the multi-film with the harvester with the take-up device attached. Preferably, harvesting is performed.
